 I think you are correct that linux/limit.h is the problem.  Looking
at one of my x86_64 7.6 logs, the linux headers installed
/usr/include/linux/limits.h [ as well as a lot of other files there,
and directories /usr/include/asm /usr/include/asm-generic
/usr/include/drm /usr/include/mtd /usr/include/rdma
/usr/include/scsi /usr/include/sound /usr/include/uapi
/usr/include/video /usr/include/xen ].  Of course glibc then
puts more files into some of those directories.

 I think these fragments either get deleted immediately, or perhaps
they are somewhere in /tmp.

 Did you remove the untarred headers after installing them to /tools
in chapter 5, and then use freshly extracted source for chapter 6 ?
I do not see why that would make any difference to the headers
(unlike several other packages), but I'll ask anyway.

 Apart from that, I guess smething went wrong in
find dest/include \( -name .install -o -name ..install.cmd \) -delete
cp -rv dest/include/* /usr/include

 Maybe you missed the copy to /usr/include ?

Sometimes she went to bed as early as 6 a.m.
